Personally, it sounds like you have a lot of rage.
Nobody on the internet knows you're a dog, so any sort if personal information you provide is entirely your choice, yet from your comment we know that you are:
female
Jewish
"geek" whatever that means, specifically
lesbian
Australian
(there may be more, but honestly once I got the flavor of your screed, I skimmed since it seemed pretty much all the same).
So I ask myself, why does this individual who is in so much pain at their 'victimization' by society then proceed to identify every possible characteristic that might then (if society is as biased as they claim) cause the rest of us 'normal people' to disregard her/his/its* voice?
*please pardon me if my application of pronoun in your case is justifiably tentative
I'm honestly curious?
If 'nobody is listening' to these marginalized categories of people, if you're actually working for change, why
Or, is it perhaps just a giant cry for attention?
The fact is that ANYONE who doesn't fit the 'norm' of a group will stand out to some degree. Male nurses for decades weren't (and in some places, still aren't) taken seriously. Male teachers are still often regarded in some districts as inappropriate for younger children. Show me a stay-at-home-dad that hasn't felt excluded from the social circle of playground parents?
One can make the best of it, and try to slowly change the norm. It's not something that's going to happen in a year, or a decade, or even in one lifetime, as frustrating as that may be to people who WANT THAT RIGHT NOW (ie 99.9% of the population today).
I know I'm going out on a limb here, but I'm going to venture that you're young, angry, probably have body art (piercings/tattoos/both), and often wear clothing or display bumper stickers that are confrontational about your personal choices.
I was at a fast food restaurant, and the young woman in front of me had purple- and pink-dyed hair. I thought she was rather striking, so I was probably staring. She rounded on me, confrontationally, and said "What the hell are you staring at?" My reply was "Um, because you have purple and pink hair?"
My point isn't to suggest that she SHOULDN'T have had colored hair. But to deny that she was an outlier (in this case, by her personal and demonstrative choice) would have been just silly. It's what she WANTED to be, and it seemed a little hypocritical, even in retrospect, that she should have felt entitled to 'not be noticed' when her clear choice was to BE notable.
My suggestion would be that if you spent a little less time jamming your personal life in people's faces, you'd probably find life a lot smoother and pleasant.
I know you (and a number of fellow travelers reading this) are probably in a rage now about my patriarchal tone, inferring that I'm making pejorative choices about your lifestyle. Not at all. But at a certain point you may discover that a lot of your happiness is in your own hands.
My suggestion wouldn't be to write an article about bigotry in the geek community (as you so desperately want to, but curiously phrase as a sort of 'asking for permission' thing?), spend a little less energy obsessing about how marginalized you are, and how unfair life is, and just live it. Love who you want, do what you want, be who you want and you'll be much happier.
